Rejections are hard. They are never easy. Even after a few more times, they are still hard. But notice that they have become more manageable. You are getting used to it. That bitter feeling of being rejected and having the door closed in your face. Now that that bit is settled, you can move on with pursuing your goal. Keep on at it. Keep improving your next pitch and eventually someone will say yes. If you need an added motivation, look no further to J.K. Rowling who took the world by storm with her phenomenal fiction or Thomas Edison, who you can’t really say to that you have tried enough unless you have done it over 10 000 times.
